Taking into account boundary changes caused by the creation of Xixian New District (Xīxián Xīn Qū, 西咸新区) with an end-of-2017 population of 987,800, the end-of-2017 population of Xī'ān Shì increases to 9.6167 million. The 2017 population of Xiányáng Shì decreases correspondingly to 4.376 million. Wèiyāng Qū (pop. 701,700), Cháng'ān Qū (pop. 1,009,700), Hùyì Qū (pop. 549,300), Qíndū Qū (pop. 353,000), Wèichéng Qū (pop. 216,000), Jīngyáng Xiàn (pop. 316,600) and Xīngpíng Shì (pop. 509,700) are also affected.
